MPPT Solar Charge Controller 100 Amp,Solar Panel Regulator 12V/24V Dual USB Port Solar Panel Charger Intelligent Regulator(100A,12V/24V)

When I first received this controller I wanted to test it out on more everyday used devices that use less energy. I used the controller to charge my cell phone and my headphones. Surprisingly it charged it as fast as a wall charger. I'm going to be buying another one for my chicken coop because the power is just that awesome. It is super easy to set up. I also currently have five100w solar panels connected to the charge controller and I'm quite impressed with the productivity of it. I recommend this charge controller for small projects because that's what I have tested it on.

I bought this to make a simple battery charger for farm equipment due to remote access. Some of my equipment is 24 volt, and some 12 volt. According to the information, this controller should have worked perfectly. My panel was within the parameters of the controller. The display panel would flash, and give random information, and sometimes black out completely. Connections on the unit are very simple and straight forward. Even though the solar panel was putting out plenty of voltage, the controller would send power to the battery. Useless. Buy another brand.

exactly what needed but never used

I purchased this for project im working on. This was an easy setup (ytube was helpful here). The display screen is reliable and informative. The usb ports are easily accessible. Its compact and great for small project. I'd definitely recommend

When I connected the controller to the solar panel (395w ja) the entire display flashes. The controller I am replacing works fine. I am changing controller to a higher amp rating so I can add panels. All 3 controllers act the same. With just the battery connected it shows battery voltage and the menu works, with the panel it just flashes
